He Said, She Said, No One Cares: Who is to Blame for Ryan Phillippe and Abbie Cornish Break-Up?

Initial reports indicated that Cornish finally realized she was dating a cheater whose real-life personality isn't all that different from his character in Cruel Intentions.

“Abbie has always questioned Ryan’s loyalty. How could she not? When she began dating him he was married, she’s a smart girl," a source told OK! Weekly. "She knows men don’t change, she hoped he would, but she always knew deep down this wasn’t forever.”

HOWEVER, a friend of Ryan's says otherwise. This insider told Hollywoodlife.com that Phillippe was the one who called it quits.

“Ryan ended the relationship recently while she was in Australia. He asked her to remove her belongings from his house, which she did this weekend," the source said.

So, THG readers: which side do you believe? Is Phillippe a disloyal boyfriend, or Cornish a heartbroken Aussie? Moreover, how great of a film was I Know What You Did Last Summer?!?
